Search Tone Test

Search Tone Test

A search tone test is a simple line fault locating function intended for maintenance engineers. In a search tone test, the test module sends voice signals with the specific frequency and amplitude to a line, and then maintenance engineers use a receiver or a dedicated device to detect the signals on the line. In addition, search tone tests can help maintenance engineers pinpoint the specific line among multiple user lines.

NOTE:
  • A search tone test can be performed even when a port is powered off.
  • A search tone test cannot be performed when another test task (such as a POTS user circuit test, POTS user loop line test, call emulation test, signal tone test, or POTS port loop test) is in progress.
  • A search tone test cannot be performed when a port is in the prohibit state.

Test Procedure

Figure 1-147 shows the principles of a search tone test.
Figure 1-147 Principles of a search tone test

  1. The test module sends voice signals with the specific frequency and amplitude (as underlined by blue wave lines in Figure 1-147) to a line after a search tone test is started.
    In test mode, run the pots search-tone-test frameid/slotid/portid test-flag enable command to start a search tone test. If users are making calls during a search tone test, maintenance engineers can cancel or forcibly perform the test based on actual conditions.
    NOTE:
    If maintenance engineers forcibly perform the test, services on the port are interrupted and users' telephone services are affected. Therefore, exercise caution when performing this operation.
  2. Maintenance engineers use a receiver or a dedicated device connected to the other end of the line to detect whether the voice signals can be received. If the voice signals can be received, the line works normally.
  3. (Optional) Stop a search tone test.
    Run the pots search-tone-test frameid/slotid/portid test-flag disable command to stop a search tone test.
    NOTE:
    In a search tone test, the duration of playing the search tone needs to be set based on actual requirements.
    • If the preset duration does not expire, maintenance engineers can run this command to manually stop the test.
    • If the preset duration has expired, the system automatically stops the test.
